Last Friday night, MLB Network unleashed their Top 10 First Basemen Right Now along with input from host Brian Kenny, former MLB first baseman Sean Casey, and special guest Bill James. Throughout the series, I’ve had some issues with their inconsistency regarding guys with multi-eligibility. I felt they set a precedent with the initial show by placing Shin-Soo Choo among the centerfielders. That will be his 2013 position so I figured that’s how they’d operate moving forward, but instead they’ve been all over the map.

There were no such issues at first base. In fact, there was very little disagreement among which 10 players should be included. Rankings were different, but I only had one difference with three of the four lists and just two with the fourth.

Here are all four lists from MLB Network-related folks and then I’ll address them separately:

The Shredder

My only real issue here is that Mark Teixeira is a bit high for me. I’m sure it’s the reputation of his exemplary glove. And it is good, but his bat is now one dimensional as he has become a .250ish hitter. His walk rate is on a 3-year downswing, too, eating into his OBP. He’s just not the superstar he once was back in his mid-20s. I was thrilled to see my boy Allen Craig get so much love. In fact, this is lowest he was rated besides my #9 ranking. I think I was trying to self-censor myself and make sure I didn’t overrate him.

My inclusion they didn’t list: Freddie Freeman

Sean Casey

This might be the best list of the entire series! Of course I only say that because it is arguably the most similar to mine that we’ve seen. We matched our top four and the only big divergence was that he rated Craig much higher which of course I’m more than OK with. Adam LaRoche over Freeman is completely defensible.

My inclusion he didn’t list: Freeman

Bill James

I’ve had the biggest issues with James’ lists throughout this series. I think he’s made some terrible picks and knowing his background, I can’t figure out how he’s coming to the conclusions. First base was no different. Anthony Rizzo is really better than Edwin Encarnacion and Craig? After 87 games? Really, Bill? C’mon. How on earth is Joey Votto third? This is just one of those where it’s not really an opinion thing. All of the data, which you’d think he favors, points to Votto easily being the best 1B right now. I was pretty geeked when I saw that James was going to be a part of the series, but it’s been a total dud for me. His reasoning is often shoddy (again, massively surprising given who we are talking about here) and he’s just all over the map.

With 30 days to go, I started profiling a hitter per day highlighting one from each team. I selected my player of note from each team and then randomized them (which was pretty interesting consider who the final two were after the randomization) so that’s the order I’ll be following.

ANTHONY RIZZO

One of the winter’s rising sleepers (which of course cuts into his sleeper value) is Chicago Cubs first baseman Anthony Rizzo. He had a brief, but ugly debut in 2011 that saw him hit just .141 with a 523 OPS in 153 plate appearances with the San Diego Padres. Jed Hoyer, formerly of the Padres, joined forces with Theo Epstein to run the Cubs that offseason so they wanted to get their prized prospect, whom they’d discovered as part of the Boston Red Sox organization when they drafted him in 2007. He was traded for that offseason and instantly became part of their future foundation with Starlin Castro.

Rizzo ripped through the PCL in 2011 with 26 home runs, 101 RBIS, and a 1056 OPS in 413 plate appearances and yet he somehow topped that in his follow-up as a Cub farmhand hitting 23 home runs, driving in 62, and posting an 1101 OPS in just 284 plate appearances. He’d have been called up earlier, but Bryan LaHair was having an unexpected great start to the season. Once he reached the majors again on June 26th, he showed that his 2011 flop was merely a blip. He hit .285 with 15 home runs, 48 RBIs, and an 805 OPS in 368 plate appearances. His seven percent walk rate was below average, but the 17 percent strikeout rate was very good (3% better than league average for the position).

A lot of outlets are looking for a big breakout in 2013 now that he will have a full season of playing time. The Bill James projection at Fangraphs has him down for a .283-33-109 season. Yes, really. The “Fans”, which consists of 41 Fangraph reader projections, weren’t far from James at .285-28-103. Those are definitely… optimistic… to say the least. I can’t help but wonder if we, the baseball community, learned nothing from last year. Doesn’t Rizzo fit the mold of some heavily favored sleepers from 2012? Namely guys like Eric Hosmer, Brett Lawrie, and Desmond Jennings?

They were the shiny new toys of 2011 with various levels of kick-assery and they became the object of many fantasy managers’ affection leading into the March draft season for 2012. Hosmer had more or less a full season logging 128 games and 563 plate appearances while Lawrie and Jennings merely gave a taste at 43 and 63 games played, respectively. And how did that all work out?

Hosmer is least like Rizzo from an experience standpoint, but most like him in every other avenue as the pair are both 23-year old left-handed first basemen. Hosmer had the relatively full season of success in 2011, but that second time around the league was brutal as the struggles against lefties continued and he couldn’t stay great against righties. His 886 OPS against righties dropped to 700 in 2012 while his performance against lefties improved just six points to a still-meager 591 OPS.

Rizzo posted an 892 OPS against righties in 2012 compared to just 599 against lefties. As lefties with groundballs tendencies, they are going to be more susceptible to the infield shift. I don’t know how much either Hosmer or Rizzo faced the shift in 2012, but I do know they hit .091 and .161, respectively, on grounders to the pull field against lefties. It’s a thin slice of data as they had just 44 and 31 such plate appearances, but still worth noting especially if either or both weren’t facing the shift often.

League average for lefties in those situations was .174 so Rizzo wasn’t too far off, but his margin for error is scant if he is to have the breakout season projected at Fangraphs as he can’t give anything back against righties (and probably needs to jump up some) and needs massively improve against lefties. He was great in a half of 2012, but it is a lot different going through the grind of all six months in the big leagues. Even hitting the extrapolation of his 2012 numbers would be a major achievement.

Taking his 2012 rates over 630 plate appearances yields a 26 homer/82 RBI season which would be fantastic for the 23-year old and I still think that should be on the outer end of his projection. After all, look what another sweet-swinging first baseman did in 2012 compared to his 2011 extrapolation. Paul Goldschmidt skipped Triple-A in 2011 coming up to the bigs for a 177-plate appearance carafe of coffee during which he crushed eight bombs with 26 RBIs and a .250/.333/.474 line. Extrapolating that out would’ve been a 28/93 season yet he was far from a disappointment when he “only” went 20/82 last year. (Sidenote: I’ve got more on him coming up soon. Big fan. Big, big fan.)

The extrapolation game with youngsters is dangerous, and frankly kind of stupid. We already know that they aren’t guaranteed to progress in a linear fashion thus expecting someone like Rizzo to essentially just double his 2012 production in his first full season at such a young age is foolhardy. In order to hit any of these home run projections, he’s either going to have to maintain his 18 percent HR/FB rate or add some flyballs to the 30 percent he hit last year. He wasn’t struggling to hit the ball hard with an awesome 24.4 percent line drive rate, but sustaining that over a full season won’t be easy, either.

Just 10 percent (14-of-143) of qualified hitters were at or above his 24.4 LD rate meanwhile only four of those players were at or below his 30 percent flyball rate. So it’s basically one or the other. Two of them were Buster Posey and Robinson Cano, so there is precedent for Rizzo… as long as he’s an all-world player. And only six players maintained an 18.1 HR/FB rate or better with a flyball rate south of 30 percent. Posey and Cano were two of them along with David Freese, Kendrys Morales, Billy Butler, and Carlos Gonzalez. Note that none of those players were both 23 years old and entering their first full year in the majors.

Despite the negative slant to this piece, I’m not down on Rizzo’s long-term prospects at all. I’m simply preaching caution with him for 2013. Last year wasn’t the first year that prospects failed to live up to their billing, but rather the most recent examples thus they’re still fresh in our memories. We should learn from last year’s mistakes, not make them again. Sure there is going to be some under-25 stud who tears the league apart, but betting a significant amount of your auction budget or a high round draft pick that you found the needle is a good way to finish sixth.

One final note is that obviously all bets are off in keeper and dynasty leagues as you’re going to have to pay a little more on the front-end to enjoy the future. In current keeper & dynasty leagues, he is already cheap and likely not for sale, but in new leagues he will have a bit of an elevated price based on his hot 2013, age, and overall prospects. If you are the type who likes to build the future juggernaut in those leagues, he’s definitely one to target.

Here are this week’s MLB Sunday Twidbits which is something I’ll be doing every Sunday throughout the baseball season. It’s a simple exercise whereby I tour the league giving a statistical tidbit per team on Twitter feed (@sporer). Sometimes a team or two will get more than one if I have more than one nugget I really want to share, but every team will be represented at least once.
